Setup JMX exporting in Wildfly 15 domain configuration with JDK11

Question

I'm trying to setup JMX exporting to plug in Prometheus metrics. Wildfly 15 with Java 11 is used. In domain config I have such a block:

<jvm-options>
                    <option value="-Djboss.modules.system.pkgs=org.jboss.byteman,org.jboss.logmanager"/>
                    <option value="-Djava.util.logging.manager=org.jboss.logmanager.LogManager"/>
                    <option value="-Xbootclasspath/a:/opt/wildfly/wildfly-15.0.1.Final/modules/system/layers/base/org/jboss/logmanager/main/jboss-logmanager-2.1.5.Final.jar:/opt/wildfly/wildfly-15.0.1.Final/jboss-modules.jar:/opt/wildfly/wildfly-15.0.1.Final/modules/system/layers/base/org/slf4j/impl/main/slf4j-jboss-logmanager-1.0.3.GA.jar:/opt/wildfly/wildfly-15.0.1.Final/modules/system/layers/base/org/wildfly/common/main/wildfly-common-1.4.0.Final.jar"/>
                    <option value="-javaagent:/opt/wildfly/wildfly-15.0.1.Final/jmx_prometheus_javaagent-0.3.1.jar=58080:/opt/wildfly/wildfly-15.0.1.Final/jmx_prometheus.yml"/>
                </jvm-options>

This setup works fine with Java8, a similar setup works fine in Wildfly 10. But the Wildfly15+Java11 bundle results in such an error:

[Server:wf01] Exception in thread "main" java.lang.IllegalStateException: The LogManager was not properly installed (you must set the "java.util.logging.manager" system property to "org.jboss.logmanager.LogManager")

Tried various workarounds found all over the Internet but to no avail. Any clues?
